What would happen if the worlds population immediately doubled?

Answer 1

We would run out of food, water and all resources after only a few weeks. Not to mention that almost everywhere would become critically over-populated and the homeless rate would sky rocket. The human population already went up by 6x the normal rate in the early 19th century, and shows no signs of shrinking.

Answer 2

An immediate doubling of the world's population would put immense strain on resources such as food, water, and energy. There would likely be widespread challenges related to overcrowding, competition for resources, and environmental degradation, leading to potential social, economic, and political disruptions. Governments and societies would need to quickly adapt and implement sustainable measures to support such a large population increase.
